Sen. Bill Cassidy's 2026 primary looms as Rep. Julia Letlow considers running

Rep. Julia Letlow is seriously considering mounting a primary challenge against Sen.

Rep. Julia Letlow is seriously considering mounting a primary challenge against Sen. Bill Cassidy, her fellow Louisiana Republican, according to three GOP sources familiar with the matter. And she has received encouragement from the White House to jump into the race, two sources said.

Letlow, 44, has been weighing her options carefully over the past few months but has not put a timeline on making a decision, though sources say she has grown more serious about the idea of running for the Senate.

Cassidy, a physician, has recently been in the spotlight taking on Health and Human Services Secretary Robert F. Kennedy Jr. over vaccine policy.

But even with a trio of Republican candidates already in the race, Letlow, who was seen meeting with a GOP megadonor this week at the Capitol Hill Club, has been the subject of recruiting efforts.

She could be a formidable challenger to Cassidy — especially if she has Trump’s backing. One of the GOP sources said the White House has assured Letlow that its support would be there if she chooses to jump into the race.
